Our help-center lists explicitly one symptom that makes a question "off-topic":
Questions answered by a simple Google search or to be found in a Wikipedia page
I see 'a problem' there.
First, the capitalised word "Google" is really an advertisement, unpaid, for one search engine. It is not the genericised 'to google something' (meaning searching the net via an/any engine).
It almost follows from concentrating on this 'evil' engine that we disregard two aspects:
What in general is meant with "simple search"?
(First "I'm feeling lucky"-hit after entering a single search string? First 3–5 hits? First 3 pages of entering up to 5 keywords or the entire actual question into the search fields?)
Results from Google are not universal!
The results depend on a long list, not entirely public, of parameters.
It is known that results presented depend on region and/or IP, local censorship or other laws, cookies set in browser (also from other sites?), status of logged-in or not, personal search history and more (company doing experiments).
Most bluntly: US users see different results compared to EU citizens or compared to Chinese users? We cannot blindly rely on two people from different parts of the world using the exact same search string to get identical results from Google.
To be clear: other search engines might suffer from this phenomenon as well, although to a much lesser degree. But the point to observe is that two users using Google might see a different list, with different results or in a different order — much like two users using entirely different search engines: dynamically generated content is not a shared and stable frame of reference.
(Apart from making Google results generally less reliable than many might think this also paints the common phrasing in many comments less ideal than they are intended to be: ~"literally the first link on Google" — is really just the same as "what I found". A conclusion from that alone that 'OP didn't search/google' is not necessarily true (although I agree that it makes OP's prior research somewhat less likely to have been done. Again emphasising that this kind of prior research needs more explicit mentioning in any question?)
(Apart from suggesting that we re-word the free ad for Google in the help page; there are alternatives)
What research effort by a poster do we consider "answered by a simple search"?
